So I have recently converted a carport into a barn and have used standard steel siding with a factory painted finish on it. My friend had a bunch of siding left over from a project he was working on and gave it to me to use so now I have a mix match of white and red metal siding on my barn and I am wanting to paint it to make it all "barn red". I plan on using a sprayer to paint the metal but here are my questions:
1) The metal is pretty new and still has a shiny new surface to it. Do I need to do anything other than power wash it to make sure the paint sticks to the surface?
2) Is acrylic paint the best way to go when covering a steel siding?
3) If I use acrylic paint do I need to do anything to the paint to make sure it comes out of the sprayer and does not clog up the sprayer? I have always brushed or rolled paint never used a sprayer before.
Thank you for your help!!!
